在C#中嵌入IronPython的问题(缺少编译器所需的成员'Microsoft.CSharp.RuntimeBinder.Binder.InvokeMember'

Question

我正在尝试做一个简单的hello世界来测试在C#中嵌入IronPython但似乎无法解决这个问题.

这是我的C#文件;

using System;
using IronPython.Hosting;
using Microsoft.Scripting;
using Microsoft.Scripting.Hosting;
using System.IO;

public class dynamic_demo
{
    static void Main()
    {
        var ipy = Python.CreateRuntime();

        dynamic test = ipy.UseFile(@"../../Test.py");

        test.Simple();
    }
}

这是python类;

import sys

def Simple():
    print 'Hello from Python'
    print "Call Dir(): "
    print dir()
    print "Print the Path: " 
    print sys.path

我的目标.NET框架是4.0,我正在使用IronPython 2.6 ..

当我运行这个时,我得到2个错误来自一个名为"CSC"的文件; 错误5缺少编译器所需的成员

'Microsoft.CSharp.RuntimeBinder.Binder.InvokeMember'C:\ Users\Tolga\documents\visual studio 2012\Projects\WindowsFormsApplication1\consoleTest\CSC consoleTest

另一个来自我创建的C#文件

错误6无法找到编译动态表达式所需的一种或多种类型.你错过了参考吗？C:\ Users\Tolga\documents\visual studio 2012\Projects\WindowsFormsApplication1\consoleTest\Program.cs 17 9 consoleTest

这是Build的输出

Answer 1

您需要添加引用Microsoft.CSharp.dll.这提供了dynamic在C#中使用所需的类型.

此外,您可能需要升级到IronPython 2.7 [.3]或更高版本,因为与旧版本和较新的.NET框架存在一些不兼容性.
